Hello Wrenches,<br><br>
Power One tech support said that full sized neutrals had to be run to a
pair of 240 V, PVI 3.6 inverters. We have a 180 foot underground
run to the service panel. <br><br>
Why do we need to run a full sized neutral all the way back to the
panel? The wiring to the panel is oversized for voltage drop.
The code allows for reduction of neutral size where neutral imbalance is
less than the current of a phase, which is usually the case. <br><br>
Why does a neutral need to be installed that is the size of the phase
wiring where the imbalance should be negligible? Or is there a lot of
neutral current for some reason? Am I missing something?
<br><br>
Thanks<br><br>
